Nigerian Breweries Plc , the nation’s largest brewer by market value, said bombings and attacks by Boko Haram Islamists are curbing sales in the north.

“People are more reluctant to go out and retail sales in the more insecure areas are under pressure,” Chief Executive Officer Nicolaas Vervelde said in an interview yesterday in Lagos,Nigeria’s commercial capital. The north, which had been growing “in line” with the rest of the market through malt drinks in recent years, “is doing less than what we see elsewhere in the country,” he said.

Authorities in Africa’s biggest oil producing country blame Boko Haram for a surge in bomb and gun attacks in the country’s mainly Muslim north and Abuja, the capital, in which hundreds have died this year. The group, whose name means “Western education is a sin,” claimed responsibility for attacks that killed 256 people in January in Kano, the biggest city in the north, and last year’s suicide car-bombing of the United Nations building in Abuja that killed 24.

PZ Cussons Plc , the U.K. maker of soap that gets the greatest share of its sales from Africa, said in a statement in March that its performance would be “some way below expectations” because of turmoil in the north.

Nigerian Breweries, which is a unit of Amsterdam-based Heineken NV, has advanced 19 percent this year, twice the 8.7 percent gain for the Nigerian Stock Exchange All-Share Index. First-quarter profit jumped 16 percent from a year earlier, while revenue climbed 29 percent.

‘Robust Growth’

Even with the violence in the north, the company expects second-quarter earnings to continue to expand at a similar pace to last quarter, Vervelde said, with its Star lager leading sales.

“The fundamentals of the market are still good,” Vervelde said. “If you compare that with what’s happening in Europe, it’s robust growth.”

Nigeria’s economy is forecast to grow 6.5 percent this year, according to the National Bureau of Statistics, with the nation’s population of more than 160 million expanding 2.5 percent a year, World Bank estimates show. The European Commission forecasts 0.3 percent growth for the European Union’s economy this year.

Nigerian Breweries last year acquired Sona Systems Associates Business Management Ltd. and Life Breweries Co. to expand its capacity and extend its brands. The company has invested about 100 million euros ($130 million) annually on average over the past five years, a trend that may continue as the company expands capacity at newly acquired breweries, Vervelde said. The company currently operates eight brewing plants in Nigeria.

‘Young Demographics’

Nigerian Breweries is “open to any opportunity” to continue expansion through acquisitions, said Vervelde.“The market has become far more competitive.”

SABMiller Plc, the world’s second-largest brewer by volume, is building a $100 million plant in Onitsha, in south-eastern Nigeria. Guinness Nigeria Plc, a beer-making unit of distillerDiageo Plc , said last year that it will spend $336 million to expand brewing capacity in the country.
